Left:	konsole
Middle: xterm
Right:	mlterm

Font is always

/usr/X11R6/lib/X11/fonts/misc/9x15.pcf.gz 

also known as

/opt/kde3/share/fonts/9x15.pcf.gz (almost identical copy)

when using X11 core fonts the XLFD of this font is:

-Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO10646-1

The screen show shows that all these combining characters are
displayed correctly in xterm and mlterm bug only very few are
displayed correctly in konsole.

It is not that konsole doesn't support combining characters at all, it
does display a few of them correctly and apparently always calculates
the columns used correctly.

But nevertheless, most combining characters cannot be displayed correctly.

Playing around with different fonts doesn't help.

And I am pretty sure that the font used in the screen shot is the
same for all 3 terminals.

Same bug also reported here: http://bugzilla.novell.com (bug #80623).

Konsole applies NFC and discards further combining chars.
